I have done NR==FNR earlier for a single column data, but I dont know how to get multiple column data using NR==FNR method.
The closest thread is this Join 2 files with multiple columns: awk/grep/join? - The UNIX and Linux Forums , but gives slightly different output than the one I need.
Hoping that someone can help. awk seems so much nicer than doing this in excel using VLOOKUP. Files are not sorted and duplicate lines are not expected.
Thanks

Try this:
Code:
awk 'NR==FNR{s=$1; sub(".*"$2,"");a[s]=$0; next}
a[$1]{print $0 a[$1]}
' bar.txt foo.txt

Franklin,

So I tried that with the sample data as provided here and it worked perfect.
I ran the same on my actual data (having the exact structure as given here) and it did not work. Here is the output I got. It gave the two strings on different lines on my Windows Text editor Notepad++
When I opened it in vi, I found a character 1^M at the junction between the 1st and second file.
I found another thread here that dealt with the same string problem. http://bit.ly/cq0JaJ
I used the first solution by anbu23 and it worked for me.

I know the data is same structure.. I copy pasted the first 5 lines. Though wondering if the tabs may have been a problem when pasting to windows?
Any ideas or different code?
Code:
    -0.0053     -0.0046      0.0036     -0.0059      0.0019      0.0029      0.0022      0.0078      0.0043     -0.0001          Control

It seems that it doesn't print the lines ($0) of the second file.
Code:
print $0 a[$1]

Have you type the command correctly?

Hi Franklin52,

The script worked fine, it prints both the 1st and the second file. However, when it joins the first and second file, there is a character ^M in between that makes the second file to be printed on the next line in DOS.
I used the solution by anbu23 as mentioned in the previous post to solve it.

I tried to understand this code, not smart enough.
Can someone please help.
Thanks

Code:
awk 'NR==FNR{s=$1; sub(".*"$2,"");a[s]=$0; next} a[$1]{print $0 a[$1]} ' bar.txt foo.txt

Code:
awk 'NR==FNR{s=$1; sub(".*"$2,"");a[s]=$0; next} a[$1]{print $0 a[$1]} ' bar.txt foo.txt

Explanation:
Code:
NR==FNR

If we read the first file.
Code:
s=$1

Capture the first field in variable s to use it as an index of the array a.
Code:
sub(".*"$2,"")

Remove the first 2 fields
Code:
a[s]=$0

Store the the value of $0 in element a[s]


Code for the second file:
Code:
a[$1]{print $0 a[$1]}

If the first field is an index in array a print the line and the content of the element of the array.
